摘要

目标确定影响乌克兰肉猪品种补偿性生长和生产性能的因素。利用几个生长发育指标,分析不同年龄段选择性状对猪活重的影响。为了确定两组仔猪的补偿生长(基于它们的个体重量,相对于平均日增重(ADG),高于一窝仔猪的平均平均体重(M+)或低于一窝仔猪平均体重(M-)),以便在特定的育种计划中使用这些因素。方法。使用Eletor SC-12(波兰)设备维持饲养实验仔猪的均匀小气候条件。在为研究组选择动物时,通过直接观察确定了生理条件(通过直接观察)、年龄(根据主要动物技术记录)和电子秤(Axis(乌克兰))上的活重称重,测量精度为0.02公斤。我们的研究基础是乌克兰肉种猪的活重,n=381只。形成前两组仔猪(M+;M-)n=143(М+);n=158(М-);基于它们的个体重量,高于一窝平均仔猪重量(M+)或低于一窝平均小猪重量(M-)。此外,后来根据存在或不存在补偿生长形成了两组(M++、M+-、M-+和M--)n=66(M++)、n=77(M+-)、n=68(M-+)和n=90(M--)。后果与其他组相比,处于养育阶段的M++组在2-6个月大时,在2-4个月期间表现出22.2%(P<0.001)的平均日增重,在4-6个月期间显示出8.8%(P<0.01)的平均增重。方差分析显示,60~120天补偿生长增重的变化影响3~8月龄猪的活重(P<0.001)。60天仔猪平均一窝活重的变异性影响3~7月龄猪(P<001)和8月龄(P<0.05)的活重,而这两个因素之间的相互作用影响3~5月龄(P<0.001)和6月龄(P<0.05)仔猪的活重。已经获得了关于仔猪体重高于或低于平均平均产仔体重以及乌克兰肉猪补偿生长程度对其平均日增重的影响的新数据。在存在补偿生长的情况下,60日龄的M+-组动物在2-4个月期间仍优于60日龄M+-的同类动物22.2%(P<0.001),在4-6个月期间未表现出补偿生长的8.8%(P<0.01)。上述因素对2至6个月生长率的影响也得到了确定,M++组的生长率指数是M+-组的1.81倍,是M+-+组的1.54倍。窝仔组成对平均日增重(ADG)的影响最大的是在2-4个月大的时候(20.5%;P=4.2*10-12)。窝仔组成和补偿性生长(M++)已被证明是乌克兰肉猪品种的选择和育种标准,其他猪品种也可能如此,这将在未来进行研究。

Compensatory growth and piglets weight variability within the litter as breeding criteria for ukrainian meat pig breed performance
Aim. To determine the factors, affecting compensatory growth and performance of the Ukrainian meat (UM) pig breed. To analyze the impact of selection traits on the live weight of pigs during different age periods, using several growth and development indices. To determine compensatory growth by two groups of piglets (based on their individual weight, which was above the average mean piglet weight in the litter (M+) or with a weight which was below average mean piglet weight in the litter (M–), in relation to the average daily gain, ADG), in order to use these factors in a specific breeding program. Methods. Uniform microclimate conditions to rear experimental piglets were maintained using Eletor SC-12 (Poland) equipment. When selecting animals for research groups, physiological conditions were determined (by direct observation), age (according to primary zootechnical records), and live weight weighing on electronic scales (Axis (Ukraine) with a measurement accuracy of 0.02 Kg. The basis of our research was the live weight of pigs of Ukrainian meat breed, n = 381 animals. First two groups of piglets were formed (M+; M–) n = 143(М+); n = 158(М–); based on their individual weight, which was above the average mean piglet weight in the litter (M+) or with a weight which was below average mean piglet weight in the litter (M–). Furthermore, two groups were later formed based on presence or absence of compensatory growth (M++, M+–, M–+ and M– –) n = 66(M++), n = 77(M+–), n = 68(M–+) and n = 90 (M– –). Results. The group M++ at the stage of rearing, at the age of 2–6 months, exhibited superior average daily gains by 22.2 % (P < 0.001) during the period from 2 to 4 months and by 8.8 % (P < 0.01) during the period from 4 to 6 months as compared to the other groups. An ANOVA analysis showed that the changes in weight gain of compensatory growth from 60 to 120 days affects the live weight of pigs at the age of 3–8 months (P < 0.001). The variability of piglet mean live weight in a litter at 60 days influenced the live weight of pigs at the age of 3–7 months (P < 0.001) and at the age of 8 months (P < 0.05), while the interaction between these two factors affects the live weight of piglets at the age of 3–5 months (P < 0.001) and 6 months (P < 0.05). Conclusions. New data have been obtained regarding the impact of piglet weight above or below the average mean piglet weight in the litter and the degree of compensatory growth in Ukrainian meat breed pigs on their average daily gains. Animals from group M–+ at 60 days of age, in the presence of compensatory growth, still outperformed their counterparts from group M+– at 60 days of age by 22.2 % (P < 0.001) during the period from 2 to 4 months and by 8.8 % (P < 0.01) during the period from 4 to 6 months, when not exhibiting compensatory growth. The influence of the aforementioned factors was also determined on the growth rate from 2 to 6 months, with the growth rate index in the M++ group being 1.81 times higher than in the M+– group and 1.54 times higher than in the M–+ group. The highest impact of litter composition on the average daily gain (ADG) in weight was observed at the age of 2–4 months (20.5 %; P = 4.2*10–12). Group compositions towards weight above piglet average weight in the litter and compensatory growth (M++) have been shown to be useful as selection and breeding criteria for the Ukrainian meat pig breed and are possibly so for other pig breeds, which will be investigated in future.
